That article I wrote up today? Take a look at the colossal botch phys.org made of it.
Jesus fuck, how can you write for a science news site and get everything that wrong? The central dogma of molecular biology (not genetics, dinglepoofs) says that the information in proteins can’t be written back into DNA. This study doesn’t even try to address the central dogma, much less “defy” it.
Now look at this paragraph. There’s a misplaced quotation mark in there, so I’m not even sure what part is actually the words of the biologist. No, not all information is stored in DNA. The RNA editing part is not new, not surprising, and isn’t going to surprise any knowledgable biologist (the degree that some cephalopods exploit RNA is unusual, but it’s not in itself revolutionary), and most definitely does not invalidate Crick’s central dogma.
In fact, RNA editing is so rare that it’s not considered part of genetics’ “Central Dogma.” “Ever since Watson and Crick figured out that genetic information is stored in DNA, we’ve had this view that all the information is stored in DNA, and it’s faithfully copied to another molecule when it’s used—that’s RNA, and from there, it’s translated into the proteins that do all the work. “And it’s generally assumed that that’s a pretty faithful process,” explains study co-author Joshua Rosenthal, a cephalopod neurobiologist at the Marine Biological Laboratory in Woods Hole, MA. “What the squid RNA is showing is that that’s not always the case—that, in fact, organisms have developed a potent means to manipulate information in RNA.”
I’m not even going to begin on all the news stories crediting cephalopod intelligence to this process.
